Answer:
Density
Explanation:
Density is defined as the mass per unit volume. It is the ratio between the mass and the volume of a substance. It does not matter how large or small a sample of matter is, the same substance will always have the same density, because of this. The ratio between the mass and volume remains the same.
The best way to balance an equation is to balance one atom at a time.
You start with two Au atoms on the left, so you know the coefficient of Au on the right has to be 2. So at first we get,
Au2S3 + H2 --> 2Au + H2S
Then, notice you have 3 sulfur atoms on the left, so you need three on the right.
Our equation becomes
Au2S3 + H2 --> 2Au + 3H2S
Lastly, we now have six hydrogen atoms on the right, and only two on the left, so we assign a three to the H2 on the left
Au2S3 + 3H2 --> 2Au + 3H2S Is the balanced final equation.
20 protons it takes for the answer
Answer:
3 NADH molecules are made from each molecule of acetyl CoA through the Krebs Cycle.
Explanation:
First, 1 NADH is produced from each carbon lost from the 6-carbon citric acid (2 NADH total). Lastly, 1 additional NADH is made from the transformation of malate into oxaloacetic acid (acceptor molecule for acetyl CoA).
